ZyXEL G-202 User’s Guide CHAPTER 3 Wireless LAN Network This chapter provides background information on wireless LAN network. 3.1 Wireless LAN Overview The following figure provides an example of a wireless network with an AP. See Figure 2 on page 20 for an Ad Hoc network example. Figure 20 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients.
ZyXEL G-202 User’s Guide • Every device in the same wireless network must use security compatible with the AP or peer computer. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. 3.2 Wireless LAN Security Wireless LAN security is vital to your network to protect wireless communications. Configure the wireless LAN security using the Configuration or the Profile Security Setting screen.
ZyXEL G-202 User’s Guide This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized wireless devices to get the MAC address of an authorized device. Then, they can use that MAC address to use the wireless network. 3.2.3 User Authentication and Encryption You can make every user log in to the wireless network before they can use it. This is called user authentication.
ZyXEL G-202 User’s Guide • Shared Key mode involves a shared secret key to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer. • Auto authentication mode allows the G-202 to switch between the open system and shared key modes automatically. Use the auto mode if you do not know the authentication mode of the other wireless stations. 3.2.3.2 IEEE 802.
ZyXEL G-202 User’s Guide If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not. Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2. 3.
ZyXEL G-202 User’s Guide 3.3.1.2 Wireless Client Start the ZyXEL utility and click the Adapter tab. Select the OTIST check box, enter the same Setup Key as your AP’s and click Save. 3.3.2 Starting OTIST Note: You must click Start in the AP OTIST web configurator screen and in the wireless client(s) Adapter screen all within three minutes (at the time of writing). You can start OTIST in the wireless clients and AP in any order but they must all be within range and have OTIST enabled.
ZyXEL G-202 User’s Guide See the user’s guide for more information. 1 In the AP, a web configurator screen pops up showing you the security settings to transfer. After reviewing the settings, click OK. 2 This screen appears while OTIST settings are being transferred. It closes when the transfer is complete. • In the wireless client, you see this screen if it can't find an OTIST-enabled AP (with the same Setup key).

ZyXEL G-202 User’s Guide APPENDIX D Wireless Security Types of EAP Authentication This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. Your wireless LAN device may not support all authentication types. EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication.
ZyXEL G-202 User’s Guide EAP-TLS (Transport Layer Security) With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks.
ZyXEL G-202 User’s Guide For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.
ZyXEL G-202 User’s Guide TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael. They both include a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.
ZyXEL G-202 User’s Guide WPA(2)-PSK Application Example A WPA(2)s-PSK application looks as follows. 1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols). 2 The AP checks each client's password and (only) allows it to join the network if it matches its password. 3 The AP and wireless clients use the pre-shared key to generate a common PMK.
